Will a Glock 19 holster fit a Glock 45 or Glock 23?

Yes. The Glock 19, Glock 45, and Gen 3/4 Glock 23 share identical slide dimensions and trigger guard geometry, making Kydex holsters 100% interchangeable.

How do I calculate the minimum scope ring height over bore?

Minimum saddle height is calculated by subtracting the scope tube diameter from the objective lens outer diameter and dividing by 2. Add extra clearance for heavy barrel contours.

What is the difference between G1 and G7 ballistic coefficients?

The G1 standard represents flat-base projectiles, while G7 represents modern boat-tail low-drag rifle bullets. For precision long-range shooting, G7 provides significantly higher trajectory accuracy.

What reloading presses and chronographs are recommended for precision G1/G7 load development?

Competition shooters rely on single-stage presses like the Redding Big Boss II or Lyman Expert Kit Deluxe, paired with Redding Model 3 powder measures and velocity verification via calibrated Shooting Chrony F-1 or M-1 chronographs.

How should I mount a Harris bipod or Accu-Shot adapter on European match rifles?

For UIT, Freeland, or Anschutz rails, use the Harris Adapter No. 6 UIT or Accu-Shot BT28 Picatinny adapter with proper torque specs to prevent chassis stress and maintain sub-MOA repeatability.

What is the best way to clean and store precision brass and ammunition?

Utilize advanced ultrasonic cavitation cleaning baths like the Lyman Turbo Sonic 2500 alongside waterproof ammunition storage containers such as MTM Case-Gard Flip-Top P-50 and Survivor Dry Boxes.

Which paddle holsters and tactical grips provide optimal retention for duty handguns?

For Glock 17/19 and CZ/Sig platforms, combining Fobus GL-2 polymer paddle holsters with competition-grade rubberized grip panels like Pachmayr American Legend Grips and Mec-Gar steel magazines ensures rapid presentation and reliable feeding.

Range Notes & Ballistic Realities

Written by Marcus Vance, retired marksman & field consultant. No corporate talk, just cold physics from the firing line:

Trajectory Physics on the Bench

Don't trust the ammo box charts blindly. Gravity pulls every projectile at 9.8m/s², but drag is what ruins your day. If you plug a G1 BC into a long-range boat-tail calculation, your dope card will be off by yards at the 500-meter line. Keep your velocity readings fresh—ambient temperature swings of 20 degrees can shift your powder burn rates enough to cause major vertical stringing on target.

Felt Recoil vs Free Recoil

Free recoil is math; felt recoil is pain. A lightweight carbon hunting rig chambered in 300 Win Mag will kick like a mule, potentially leading to a nasty case of scope bite if your cheek weld is loose. If you build a rifle for a novice shooter, focus on adding mass to the chassis or mounting a highly efficient muzzle brake rather than just relying on soft rubber butt-pads.

Reloading Presses, Matrizen Dies & Velocity Measurement (Redding / Lyman / Chrony)

Consistent external ballistics begin at the reloading bench with precision brass sizing, lubrication, and powder dispersion. Utilizing competition-grade presses (such as the Redding T-7 Revolverkopf Wiederladepresse and Lyman Crusher II Expert Kit Deluxe) paired with Redding Pro-Series Matrizen and Imperial Sizing Die Wax (Application Media) ensures sub-tenth-grain standard deviation and long brass life. Verify your rifle and archery load developments over a calibrated optical chronograph (including Shooting Chrony Mod F-1, M-1, and Archery Chrony Master series) to measure exact velocity (fps / m/s) before generating your G1/G7 DOPE card.
